プ。[Claims for Utility Model Registration] 1. In a submersible motor pump equipped with a pump section at the lower end of the motor, a rib is provided intermittently at the lower end of the pump casing, and a floor plate is installed at the lower part of the rib slightly above the floor surface. 1. A submersible motor pump, wherein the submersible motor pump is attached to a position, the opening of the bottom plate and the suction port of the pump casing are connected by a cylindrical body, and the cylindrical body forms part of a suction flow path. 2. The submersible motor pump according to claim 1, wherein the bottom plate is installed at a height that allows it to suck in liquid on the floor surface with almost no residual liquid. 3. The submersible motor pump according to claim 1, wherein a suction check valve is housed inside the cylindrical body forming a part of the suction flow path. 4 The suction check valve housed in the cylindrical body is
The submersible motor pump according to claim 3, which is formed by placing a ball-shaped valve body on a valve seat made of an elastic body attached to an opening at the bottom. 5. The submersible motor pump according to claim 1, wherein the cylindrical body is made of an elastic body.
